Steelers safety Troy Polamalu is expected to face the Cardinals this Sunday. Pittsburgh coach Mike Tomlin said Polamalu is "good to go" after passing a concussion test. The team removed the veteran from the game midway through the fourth quarter of Sunday's 17-13 win over the Jaguars because of concussion-like symptoms. Tomlin believes Polamalu was injured while diving at Jones-Drew's legs on a third-and-1 play. Polamalu stuffed Jones-Drew no gain, forcing the Jaguars to punt.
